Try it: fit a 3D venue scan to a size budget

This is the working version of the 3D venue tutorial. It opens the sample scene or a file of your own, shows how many Gaussians it holds and how many bytes that is, and keeps only as many of the most important Gaussians as your size budget allows. Then it gives you the scene.splat you would publish.

Your file never leaves this tab. The lab reads the file in your browser and uploads nothing. It reads a 32-byte-per-Gaussian .splat file or a trained .ply file of up to 250,000 Gaussians. Reload the page to forget it.

One megabyte here is 1,000,000 bytes. A budget is a limit you choose; pick one before you look at the scene.

How this lab works

Counts come from the file. The Gaussian count is the file size divided by 32, so the table always matches the file you opened.
Importance is opacity times volume. A large, solid Gaussian covers more of the picture than a small faint one, so the budget removes the faint small ones first. It is a simple rule, and it can leave holes.
Colour is flattened. A trained .ply stores colour that changes with the viewing angle. The conversion keeps the base colour only.
Edit and the result goes stale. Change the budget and the download switches off until you apply it again.
Local files only. The viewer is our own script served from this site, so nothing loads from a content network.
